This one needs environment variables set before it will start: X402_WALLET_PRIVATE_KEY (EVM wallet private key used to sign x402 USDC micropayments on Base (required for pay-per-request mode)), CHAINANALYZER_API_KEY (ChainAnalyzer API key (tfk_...) for subscription-based billing instead of x402 micropayments), CHAINANALYZER_BASE_URL (Override the API base URL (default: https://chain-analyzer.com)). The author declared them in the registry entry; get the values from the project itself.

Chainanalyzer MCP — questions

Answers built from our own checks of this server.

Why is there no uptime for Chainanalyzer MCP?

Chainanalyzer MCP runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package chainanalyzer-mcp was installed 43 times last week.

How do I connect Chainanalyzer MCP?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls chainanalyzer-mcp straight from npm; nothing to host, nothing to sign up for.

How many people use Chainanalyzer MCP?

The npm package chainanalyzer-mcp was installed 43 times in the last week. Week over week that is -11%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Chainanalyzer MCP open source?

Yes — it is published under the MIT licence, written in TypeScript, 1 stars on GitHub and 1 open issue. The source link is on this page, so you can read exactly what it does with your data before you connect it.
